A Pipe Schedule defines the Pipe Wall Thickness by the ANSI/ ASME B36.10M standard for Stainless Steel Pipe dimensions, and API 5L standard that depends on the nominal pipe size, internal pipe working pressure, and the material used for the pipe wall. Two pipes the same diameter may have different schedules, which means they have a different wall thickness. The list of pipe schedules used today are as follows; Pipe Schedule 5, 5S, 10, 10S, 20, 30, 40, 40S, 60, 80, 80S, 100, 120, 140, 160, STD, XS AND XXS.
